manner` previously described. ,Asg heretofore Y stated, when the belthas been shifted to the 'slow pulley, the movement of the Warp I9 andythe take-up beam I1 Will be very sloW,-and therefore, the operator canreplace l the lled beam' 40 Il with an empty'r beam without changingAthe vrspeed ofthe mechanism. If for any reason', it

should be desired to automatically stopy the mechanism when the beamreaches a predetermined size such as I9b, it Would-only bey necessary to45 adjust the collar 86 in such a position `on the v square shaft 60that a greater longitudinal movement of the shaft 60 and'belt'shifter 39Will be permitted, to permit the belt 3 6 to shift from onto the nnerpuhey e5.

After the delivery roll I4 and associated takeup beam have been sloweddown or stopped, and after a filled beam has been replaced by an emptybeam, it is kthen desired to resume the top operating speed. In order todo this, it is necessary yto release the trapped air orA iluid underpressure Ain the compression compartment II2 tofpermit the piston I`I5and-associated connecting rod IIT which is disposed at substantiallyright angles tothe port |09 previously described. When material is beingwound upon the take-up beam, the

'ports |09 and I 20 occupy the position lshown in y f Figures i and 5;whereas when the mechanism iS 70 `Second pulley for driving said beam ata reduced resuming top` speed, fthe ports are shifted from the positionshown in Figure 5 to the position shownin Figure 6. At this time, thefluid -supply fromv thepipe` 94 and tank 96 is cut'oi by the valve, butthe vrfluid from the compression k'I5 vfor admitting compressed airfrom'saidisupply l I I2, the 1 operator can then.;manually."y operatethe yAs. va means?r` forlubricating interior-.of :the 'cylinder-1II4'and `fthe pistn'vl I5;
